What happened was I had dandruff bad and found that I had dermititis so the doctor that said that I had it said that it was caused by hormones. I didn't believe her so i tried everything -- a pokeroot concoction to meds. I did not like the meds I was on, so I soon found out that SD was caused by a fungus infection so I found a shampoo that had not long chemical names and put half a 4 oz bottle of dmso in it. Within a week it was gone and has been for almost 5 months. dmso will pull anything into your skin so no long named chemicals.
